Modern morphometric-based approaches provide valuable metrics to quantify and understand macroevolutionary and macroecological patterns and processes. Here we describe TriloMorph, an openly accessible database for morpho-geometric information of trilobites, together with a landmark acquisition protocol. In addition to morphological traits, the database contains contextual data on chronostratigraphic age, geographic location, taxonomic information and lithology of landmarked specimens.

- The Early Ordovician period is important for understanding life evolution on Earth, marking a shift between the Cambrian Explosion and the Ordovician Radiation, with limited fossils from the late Cambrian.
- This study investigates the assembly of trilobite and echinoderm communities in regions across Morocco, France, and Argentina, revealing that trilobite dispersal increased over time, while echinoderm dispersal remained constant.
- The findings suggest that the rise in trilobite dispersal was influenced by various factors, like changes in ocean conditions and tectonic activities, indicating a complex ecosystem structure during the initial phases of the Ordovician Radiation.
Trilobites, key components of early Palaeozoic communities, are considered to have been invariably fully marine. Through the integration of ichnological, palaeobiological, and sedimentological datasets within a sequence-stratigraphical framework, we challenge this assumption. Here, we report uncontroversial trace and body fossil evidence of their presence in brackish-water settings.
